To all whom itma concern:

"Be it known. t at I, WILLIAM H. Gom- SMITH, Jr., of Biddeford, in thecount of f the York and State of Maine, a citizen 0 United States, haveinvented a new and useful Improvement in Builder-Motions, of which thefollowing is a full, clear, and exact description, reference being hadto the accompanying drawings, forming a part of this specification, inexplainin its nature.

My. invention relates to a bullder motion adapted to make either afilling wind or a warp wind.

The essential object of my invention is to provide a builder motioncapable of considerable variation in the production of a filling windfor varying the character of such wind, and which builder can easily beconverted into one for making a warp wind.

The invention can best be seen by reference to the drawings in which anembodiment thereof is shown and such portion of a spinning frame as isincidentally used for supporting various parts of the builder.

Figure 1 shows the builder in side elevation. Fig. 2 is a section on theline 2-2 of Fig. 1. Fig. 3 is a section on the line 33 of Fig. 1. Fig. 4is a forward end elevation of the builder, other parts to whichreference will hereinafter be made being shown in side elevation. Fig. 5is a front elevation of a detail of construction to which specialreference will hereinafter be made. Figs. 6, 7, 8 and 9 are diagrammaticside elevations of the builder showing certain varia tions obtained inthe operation thereof for varying the character of the wind as willlater be more fully explained. Figs. 10 and 11 are side elevations ofthe builder when altered to make a warp wind.

Referring to the drawings :1 represents the builder arm; 2 the stud onwhich the' arm is pivotally mounted and which has any suitable fixtureor base of support as a frame 3 which corresponds with the end of aspinning frame. The builder arm is overweighted by a weight 4' on theend thereof.

Arranged upon the rear side of the I builder arm is a cam roll 5 (seeFig. 2) engaging which is a cam 6' for melting the arm. This .cam issupported and operated in any suitable manner. In the drawing the cam 15shown ivetally mounted upon a stud 7 to t frame :3. Above the builderarm 1s arranged a pulley 8 pivotally mounted to turn within a carrier9,. This carrier ism-ranged to turn within a suitable bracket 7 10 uponan axis 11 at substantially right angles to the longitudinal line of thebuilder arm. In other words, the pulley 8 not only turns this carrier,but is also arhas a curvature normally concentric with the 11abovereferred to and is mounted within a frame 16 carried by the builderarm, the arrangement of the parts being such that the rack may haveeither a forward or reverse endwise movement around the axis 11. Therack is held against lateral and edgewise displacement by the inner sideor face of the frame against which it bears, while the top and bottomedges of the rack are confined by flanges 17 and 18, respectively, whichform guides for the rack.

Pivotally secured to the rack at a point adjacent the inner end thereof,or that near- 0st the fulcrum of the builder arm, is a pulley or sheave19 around which the chain 12 is passed from the pulley 8. Secured alsoto the rack just forward of the sheave 19' is a segment 20. Thecurvature of this segment is such that the bottom edge 21 thereof maynormally present an arc concentric with the path of the rack andpractically flush with the bottom peripheral edge of the sheave 19 sothat the chain 12 after passing over the sheave 19 may thence extendoutwardly beneath the edge 21 of the segment to bear against this edge.The segment 20 is secured to the rack by screws 22, theheads of thescrews being preferably countersunk. The inner end of segment isadjutabl ing fixedly secured to the rack and also as presenting a bottomedge concentric with the path of the rack, provision is made whereby thebottom edge of the segment against which the chain bears may occupy aposition eccentric with relation to the path of the rack. For obtainingthis effect the secured to the rack, rovision being ma e for suchadjustment y slots 24 formed in the segmentthrough which the screws 22extend. These slots 24 are concentricwith the sheave 19 in orderv thatthe bottom edge 21 of the segment may always be flush with the bottomperipheral edge of the sheave, whatever the adjusted position of thesegment may be. Provision is also made whereby the end of the chainwhich connects with the holder may also have a variable point of fixturewith relation to the axis of the sheave 19 around which the chain ispassed. This effect is obtained by the formation of a relatively longvertical slot 25 in the holder, the retention of the chain beingefl'ected at any point in the holder within the extenslon of this slot.

The rack 15 is moved by means of a worm 27 on a shaft 28 journaled toturn within the builder arm. For operating this shaft there is arrangedupon the outer end thereof a ratchet wheel 29. This wheel has a hub 30through which passes a set screw 31 for fixing the wheel to the shaft.Inconjunction with this wheel is an overweighted pawl 32 pivotallysecured to the builder arm. Cooperating with the pawl 32 is a finger 33adjustably mounted on a bracket 34 having any suitable fixture ofsupport, as for example, the under side of the side bar 35 of thespinning frame, a portion of which is shown. The coordination andconsequent operation of these parts last described for effecting therotation of the shaft 28 and movement of the rack 27 need no specialdescription as they are well known to those skilled in the art.

The mechanism above described is that especially adapted for making afilling wind or that in which the ring rail has a normal relativelyslight traverse or reciprocatory movement with relation to the bobbinand also a gradual increase in elevation with relation thereto, whichwill hereinafter be referred to as gain. The extent of traverse dependsupon the extent of rocking motion imparted to the arm of the builderand,- also, upon the point where thechain leaves the builder arm withrelation to its point of fulcrumage. In other words, the traver'sedepends upon the position occupied by the sheave 19, the traverse sheaveis movedoutwardly along the longitudinal line of the builder arm awayfrom its point of fulcrumage, or diminished as the sheave is moved in areverse direc- The gain depends upon the letting out of the chain 12,the extent of gain during any interval depending upon the amount thechain is let out during such interval. For making a filling windthe-usual practice is to start with a short traverse and graduallyincrease the length of the traverse to the end of the wind. The gain,however, is largely a matter of choice, a constant or normal gain beingpreferred in some instances; a variable gain in others. Referring now tothis device in the light of these considerations, the operation is asfollows: The rack 15 is first moved inwardly in the direction of thefulcrum of the builder arm to a position where the sheave 19 will occupysuch near relative position to the fulcrum of the builder arm as'toobtain the desired initial shorttraverse. Assuming now the motion to beset in operation, the rocking movement of the builder arm tends to bringthe pawl 32 in contact with the finger 33 which. tends to actuate theratchet wheel 29 turning'the shaft 28 and worm 27 thereon and moving therack 15 outwardly upon the builder arm, thereby causing a continuingoutward displacement of the sheave 19 carried by the rack andaccordingly increasing the extent of traverse. The movement of the rackand sheave l9 and consequent increase of traverse is very slight foreach reciprocation of the builder arm and depends upon the extent ofmovement imparted to the ratchet wheel, this depending upon thegraduated or adjusted position of the finger 33 which is engaged by thepawl for actuating the ratchet Wheel. The increase in traverse issubstantially a normal increase although owing to the curvature of therack the sheave 19 will tend to move faster. along the longitudinal lineof the rack as the movement of the sheave approaches a line paralleltherewith, the tend ency of the construction accordingly being that thesheave 19 will-be moved slightly faster during a prescribed interval asapproach is made to the end of the wind, the sheave then having beenmoved to a position where its outward movement is in a linesubstantially parallel with the longitudinal line of the builder arm.

In the present device the letting out of V the chain 12 and resultinggain will de-.

pend upon a variety of considerations including the relative 1 outwardmovement of the sheave 19 along the line of the builder arm toward thefixture or holder 23 to which ment is eliminated and the chain extends.

in a direct line from the sheave 19 to the holder to which the end ofthe chain is secured As the sheave moves outwardly upon the builder arm,increasing the traverse as aforesaid, it will follow a path about theaxis 11. Therefore the portion of the chain extending between the sheave19 and pulley 8 will remain constant. 'As the sheave progressesoutwardly, howc er, the angle formed between the portion of the chainrendering onto and off the sheave 19 becomes gradually less acute,thereby tending to let out less chain. At the same time the direction orpath of the sheave 19 becomes more direct to that point of the holder atwhich the end of the chain is secured with a tendency to let out agradually increasing amount of chain, the resultant action being such asto impart a relatively slow gain substantially constant throughout,though tending to increase slightly. This gain in practice has beenfound very satisfactory and may be considerably varied bythe adjustmentof the end of the chain in the holder.

Assuming now that the segment 20 is used and is placed in a normallyadjusted position as shown in Fig. 1, or a position where that curvedportion of the chain bearing against the',under edge thereof will lie ina position concentric with the path of the rack; in other words, lie inthe path described by the sheave 19: Under these cir-' cumstances thereis obtained an exact nor-' effected, the gain being a substantiallynormal gain though slower than when the segment is occupying its normalposition asshown in Fig. '1. Assuming that the segment is adjusted to aneccentric position (to the axis 11) as indicated in Fig. 8: Under thesecircumstances there is obtained a substantiallyconstant though onefaster than that obtained when the chain is occupying its normalposition as shown in Fig. 1.

Other variations may be obtained dependchain tangentially leaves vthesegment as illustrated in Fig. 9. That is, the device shown is onecapable of efl'ecting a considerable variety in gain, and enables one'toobtain that gain which he considers to be most advantageous for hisparticular purpose.

In Figs. 10 and 11 the aforedescribed builder is shown converted intoone for making a warp -wind, slight changes only be mg necessary andthese as follows: The cam 6 is replaced by a warp-winding cam 40.

The chain 12 is fastened by a hook 41 directly to a stud 42 on thesegment 20 which isvset in a normal position as shown in Fig. 1; In casethe segment is not used then' the stud 42 may be secured directly to theside of the rack 15 as shown in Fi .11. The ratchet wheel 29 is reversedont e shaft 28 or another wheel substituted in which the teeth arereverse to those on ratchet wheel 29 as shown in Fig. 1. The changedposition of the ratchet wheel is shown in Fig. 5. In conjunction withthe wheel as changed is an overweighted pawl 43 pivotally secured to thebuilder arm and adapted to engage a finger 44. This finger is secured toa bracket 45 adjustably mounted on the frame 3 whereby the position ofthe finger 44 may be varied and the pawl 43 strike the same at differentadjusted positions of the finger for rotating the ratchet wheel andshaft 28 iii the usual manner as the builder arm is reciprocated. v

The operation is as follows: The rack is first set in a positionsubstantially as shown in Figs. 10 and 11, or in such position as willgive the proper initial traverse to the ring rail. As the builder arm isreciprocated the rack will be gradually moved inwardly by theintermittent rotation of the shaft 28 through the operation of theratchet wheel and connecting mechanism. The

effect is to gradually lessen the extent of traverse as is customary inthis kind of wind because the stud 42 with which the chain connectsbecomes gradually moved nearer to the fulcrum of the builder arm. Duringthis operation there will be no letting out of the chain beforecharacterizedas gain owing to the fact that the stud 42 remains at alltimes in the direct path of the rack or segment and at the same normaldistance from the axis 11.

It is obvious that the mechanism heretofore described may be changedwithout departing from the spirit of my invention especially withrelation to a variance in the mechanism for obtainingt'he filling windas first described, for varying the character of such wind.
